Lossless Codec Comparison

Summary

The following table shows a summary of all files in the test corpus.

Use the column headers to sort the table. Clicking on an encoder setting will take you to a page detailing the encoder and setting used, with the individual results for each file in the test corpus encoded using that encoder setting.

The Goal

The purpose of this comparison is essentially to compare the new lossless codec Yalac, written by Thomas Becker, with existing lossless codecs at similar settings.

The settings used are therefore not comprehensive, and may not represent the most effective setting for a particular codec.

Similarly, the test corpus used solely represents the type of music that I would encode. The samples are not a comprehensive collection of various music types, therefore compression ratios should not be taken as an average value, and should only be compared relatively to other codecs in this comparison.
